The answer is 2 and 1/2 years.
Well, honey, 15 months is just 1 year and 3 months. So if we want to express that as a fraction of a year, we can say it's 1 + 3/12 years, which simplifies to 1 + 1/4 years. Math can be a real hoot sometimes, can't it?
8 months is 8/120 (or 1/15, in simplest form) of a decade, since there are 12 months in a year and 10 years in a decade.
To express 2 years and 3 months as a decimal, you need to convert the months into a fraction of a year. Since there are 12 months in a year, 3 months is equal to 3/12 or 0.25 years. Adding this to 2 years gives a total of 2.25 years, which can be expressed as a decimal as 2.25.
10 months as a fraction of 2 years
To convert 4 years and 3 months to a fraction, we need to consider the total number of months. 4 years is equal to 48 months (4 years * 12 months/year), and adding 3 months gives us a total of 51 months. Therefore, 4 years and 3 months can be expressed as the fraction 51/12, which simplifies to 4 3/12 or 4 1/4.
3/4
18 months
The answer would depend on what period of time you are wanting to express, but let us suppose, for example, the unit was years. You would write this as 15/12 of a year. You could then simplify this to 5/4 of a year or 1 1/4 years.
1 year = 12 months11 months is 11/12 fraction
32/1 months.
The answer depends on what period the given length of time is meant to be a fraction of.
